7 Claims.

- 1 This invention relates generally to means whereby a normal sizebedstead may be lengthcned and more particularly to a device forextending the bed rail of the standard type bedstead.

' The primary object of this invention is to provide a device which canbe readily attached to a bed rail and which will thereby extend thelength of said bed rail whereby the length of the entire bedstead willbe increased making it possible.

to accommodate therein a person of tall stature.

Another object of the invention is to provide a simple device of thecharacter described which will be simple and eifective in operation andeconomical to manufacture.

Another object of the invention is to provide a device of the characterdescribed, which when associated with a bedstead will be substantiallylocked in position.

A further object of the invention is to provide a device of thecharacter described which is capable of being adjusted for compensatingfor variations in the dimensions of standard bed rail connections madeby various manufacturers.

.Still a further object of the invention is to provide a device of thecharacter described which will not only lengthen the bedstead, but whichwill `cause the rails to be firmly connected with the posts thereof, andwill also be capable of being adjusted to take up wear on the connectingmembers to prevent the connection from being loose.

Still other objects of the invention are to provide a device of thecharacter described which is extremely simple to install.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel featuresof construction, arrangement and a combination of parts hereinafterfully described, illustrated in the accompanying drawing, andparticularly pointed out in the appended claims, it being understoodthat various changes in the form` proportion, size andv minor details ofthe structure maybe made without departing from the spirit orsacrificing any of the advantages of the invention'.

'*For the purpose of facilitating an understanding of mv invention, Ihave illustrated in the ac-A Referring tg the drawingin lwhich the samecharacters of reference are employed to indicate corresponding orsimilar parts throughout the t several figures of the drawing:

Fig. 1 is a perspective view showing a portion of a bedstead having mynew invention associated therewith and showing the manner in which thebed rail is lengthened thereby.

Fig. 2 is a side elevational View of the same on an enlarged scale withportions broken away and others in section to show the details thereof.

Fig. 3 is a fragmentary plan elevational view of the device of Fig. 2with portions broken away and shown in section.

Fig. 4 is a fragmentary sectional View taken generally along the line 44 of Fig. 2 and in the indicated direction.

The reference character Ill designates generally a bedstead comprising,for illustrative purposes, a heador foot-board II having corner posts,one of which is shown at I2. A bed rail I3 is shown adapted to beconnected with the post I2 and support thereon slats I4 or the like forsupporting the spring and mattress (not shown). The rail I3 has its endprovided with a metal blade member I5 of the conventional formation,having upper and lower hooks I5 and II, respectivey, and providingslanted slots I8 and I9. The post I2 is slotted as shown at 2G andcarries pins 2I and 22 passing through the post and across the `slot 20.The blade hooks I6 and Il are adapted to cooperate with the post slot2!! in such a manner that the slots i8 and I9 will engage the transversepins 2l and 22 respectively and thereby hold the bedstead in assembly.

It is sometimes desirable, where the bedstead is to be used by personswho are taller than usual, that the bedstead be longer than standard.The usual bedsteads are six feet long and will accommodate tall personsuncomfortably, and hence by means of my invention it is possible toincrease the length of the bedstead considerably, whereby longermattresses and springs may be installed, thereby accommodating suchpersons comfortably.

I provide a device 23 which is interposed between post I2 and bed railI3 and having means for cooperating with the pins 2I and 22 as well asthe blade I5 to retain the members in assembled relationship.

The device 23 comprises a shell 24 formed as a channel-shaped memberhaving a side wall 25, top and bottom walls 26 and 21 land flanges 28and 29 integrally formed with the same member' and being disposedparallel to said wall 25. Slid ably accommodated within the shell 24there'are provided two slidable members, one of which may be termed thepin member 30 and the other of which may be termed the blade member 3|.The pin member 30 is formed having a generally channel-shapedcross-section to conform with the inner cross-section of the shell 24.There is a side wall 32, top and bottom bearing flanges 33 and 34 andthe anges 35 and 3B parallel to the wall 32. The top flange wall 33extends only partially along the width of the pin member 30 so that whenthe blade I is associated therewith in a manner to be described, thespace or opening 31 permits passage thereof. Upper and lower pins 38 and39 are riveted to the wall 32 for cooperation with the slots I8 and I9of the blade I5. Centrally of the wall 32 is a lug 40 integrally formedtherewith, said lug having a screwthreaded opening therein foraccommodating therein the screw threaded end 4| of the double ended stud42. lThe opposite end 43 of said stud is similarly associated with thelug 44 of theblade member 3|. The pins 38 and 33 are each formed with ahead portion, a reduced diameter portion 45 which will be iirmlyaccommodated within the slots I8 and I9, and are riveted as shown at 46to the wall 32.

The blade member 3| is also formed of channelshaped cross-section,having the wall 41, upper ange wall 48, lower flange wall 49, upper ange5G, lower iiange 5I. An extension of the wall is bent at 52 to form ablade 53 having upper and lower hooks 54 and 55, and upper and lowerslots 56 and 51.

When the device 23 is separate from the bedstead I0, th-e assembledblade and pin members 30 and 3| readily slide-in the shell 24 and can beshipped separately. Since there is no mechanical connection between theshell 24 and the pin andA blade members, the shells 24 can all befabricated separately and the customer required to assemble same.Although the internal members must be made right and left the shells 24are the same for a pair of such devices. Thus considerable saving iseiected.

The device 23 is associated with a bedstead in the following manner:

First the blade member 3| is attached to the post I2, same having thestud 42 and pin member 3Q connected therewith. Then the shell 24 isslipped over the blade and pin members with the open portion thereoffacing inwardly of the bedstead and the slots 56 and 51 adjacent the bedrail I3. Next the hooks I6 and I1 are engaged upon the pins 38 and 39,respectively, in the process, the hook I6 passing through upper slot 53in shell 24 and through the space or opening 31. When the device is thusassembled, the stud 42 is turned by means of a wrench, pulling the lugs4E) and 44, and hence the members 30 and 3| together.Y assembled andsubstantially locked in position. t will be found that the hook I6 ismoved a sufficient distance to the right as viewed in the figuressuch-that a major portion thereof eX- tends beyond the extent of space31 thereby providing means for preventing withdrawal of the- It isbelieved that my invention, its mode "of,

The device is thus tightly- IThe described embodiment construction andassembly, and many of its advantages should be readily understood fromthe foregoing without further description, and it should also bemanifest that while a preferred embodiment of the invention has beenshown and described for illustrative purposes, the structural detailsare nevertheless capable of wide variation within thepurview of myinvention as dened in the appended claims.

What I claim and desire to secure by Letters Patent of the United Statesis:
